You made me realise that in this situation the magnet is like a pressurising head of water which never becomes reduced because it is permanently maintained, and the sudden end of armature field changes might be just like a self sustaining water hammer/ bouncing ball valve effect which relates to the oscillating length of water column (armature) delay, acting relative to a phase delayed ball valve actuation (R-L-C SS field switching?).

consider the use of one shorted coil in the following picture,
- harm in neutral position - flow straight minimum shortest route
- sharp impulse on one coil (low power because of neutral position)- crossflow
- shorted coil current reaction - inverse crossflow
ecc ..... energy recover with?

Hi Dave -
Have you checked out the 'neutral zone' of an armature or keeper yet - where fractional physical movement induces instantaneous (non-linear) armature or keeper field reversal ?

This is completely new to me, and is what I am presently investigating as per Wesley Gary's findings replicated by Chris above.

So far I have observed this positional neutral zone field alternation close to a horseshoe magnet, but as yet I have been unable to induce similar near single neodi magnets.
Nor am I aware of any neodi horseshoe magnets being manufactured/ available/ sold anywhere.

Hi Chris.

I note you mentioned making your own horseshoe magnet out of steel and neodi magnets and I can understand why.
It appears to be the asymmetry at the horseshoe poles which leads to the 'neutral zone' phenomenon developing.

I am about to try neodi magnets as pole face intensifiers on the ends of alnico horseshoes which should sink the reverse field nicely away from any working armature.

The neo's are simply too strong for this purpose. Even ceramics are at the edge of being overpowering, at least in the Gary configuration. You might try TINY neo's UNDER the horseshoe legs, i.e., at 90° to the ends.

Dave45, your intuition serves you well. However, it's not the POSITION of the COILS, it's the position of the WAVE that moves through them.

I was looking at the hendershot photo view you show in your post and it finally jumped out to me that there wasnt any capacitors inside the basket weaves! rather that was where the two transformers were placed and you could see their four wires leading in and out.! I also used the VIEW button on the top left of my computer and went to the 400% click and there is a whole lot of useful information that becomes available when you do that.

I am at presently compareing all of the wire routeing that becomes apparent! also I noticed that all of the capacitors were outside the baskets! I noticed that the magnet and bar showed that the magnet was the type with the odd magnetron shape fron a radar type magnetron setup that he had salvaged! the buzzer coil setup was built on a bolt screw type adjustable araingement.

there does seem to be a type of thin metal inner backing as an inside containment wall to the baskets. however I have not noticed any kind of wires leading from this metal area. just my observations for now I will get back with the wire routing when I am surely positive about what I see! till then LOL, mike,onward!

Hey Clarence I noticed that too, its said he built several different versions, I think the transformers would work better in the magnetic field of the basket coils than the caps.
I found these caps at mouser 1000 uf capacitor Film Capacitors | Mouser Im not sure if they will work what do you guy's think they are not electrolytic they are film used in dc filtering.

I believe this b&w photo even if looks old is not the original working device. Am I right GSM ? If so, posting such is a danger of distracting people from the right path of replicating original device into the oblivion of someone else replication attempts...

Once the system was built it would be easy to move components around, Im planning on building the basket coils on separate plexiglass sheets so I can move there positions relative to the magnet.
The buzzer coils have my attention these coils are drawing from the electric field of the magnet,
According to science a magnetic field resist's change of current flow in an inductor, the magnetic field of the magnet is resisting change in the current flow of the buzzer coils by adding to the current, this magnetic orientation needs to be studied, this shows us how to draw energy from a permanent magnet.

Hi Boguslaw.

There are only two photographs I believe to be genuine and non-distraction records of a working Mk3 Hendershot generator;-
one being the board demonstrated by Lester himself empowering a tube radio receiver;
the other being one with clamp tuning whilst an on-board lamp is illuminated.

We cannot counter the activities of those who willfully distract, and worse we cannot help those who become distracted, but PLEASE, will everybody here consider this fact -
Lester Hendershot constructed his generators using components manufactured in his day - so any circuit using 1,000uF 400Vac capacitors is NOT going to be a Hendershot generator, especially if the coil assemblies are widely separated, and not even tin/ferrous or chrome/ferrous metal cored !!!!!
Heck - anyone could run fine wires up a table leg to remotely illuminate a bank of incandescent lamps !
CRITICAL THINKING AND DISCERNMENT REMAIN ESSENTIAL AT ALL TIMES.

It has always been my understanding that field coupling between the Mk3 basket weave coil assemblies would be necessary, as indeed would have been the case with basket weave coil couplings to other windings in the Mk1-2.
Thus it is possible that Lester favoured this method of coil construction, not only because of reduced inter-turn self capacitance, but because when completed and varnished or waxed, these coils would retain their form even after the fine wooden supports had been cut away from their original construction base, hence allowing a completed assembly to be moved about and positioned as necessary.

Though stuck for 'hands-on' time here at the moment, I'm hoping to video the 'buzzer' 'neutral zone' field reversal reported by Wesley Gary, and yes Chris I do agree with you that this effect is indeed easier to observe when less powerful magnets are used.

[QUOTE=Dave45;217930]

QUOTE]

Yes a first essential step as outlined by Chris.

The buzzer coils are transducing domain alignment change withing the armature, it being the armature which 'draws' upon the magnetic field potential, through alternately induced states of physical field domain alignments, followed by motional electrical kinetic coil transduction.

Will be interesting to view your findings, thanks for sharing. This weekend I played with a previous project I have been working on for awhile, it will all come together when its time.
Im going to wind the buzzer coils this week and play with them a bit, I cant afford the caps at the moment with Christmas and all, I thought of trying to make my own and have been researching it some, it seems doable consistency would be the trick.

Check out the C1 long foil tabs emerging from the bottom of both coils !

Is this the foil which collects internally radiated charge and maintains oscillation ? Thus being both an essential input trigger terminal, as well as for observing feedback via a HiZ scope probe ?

See Crusty's own circuit drawing which he traced from the photos of this Aho generator, that might have been a self runner, if only temporary.

Is that a radio or amplifier to the right of the main board, used to listen for oscillation start-up and tuning ?
An AM radio is something I have used in the past to show whether an audio amplifier output stage is momentarily 'squegging' reactively on transients.

Good to see your links too Morpher. I studied your Hendershot vids back in 2009-10, and yes there is much to consider in relation to Lester's NOT simplistic buzzers.

Cheers ............ Graham.

Hello GSM,
clarence here,

Do you possibly know how I might get a translation in english of the AHO document in the link you show. would definitely appreciate your time and consideration concerning this. I have salvaged the two ring magnets from an old microwave magnetron and as soon as I obtain the capacitors I plan on building it. thanks much Sir! mike, onward!

PS: I believe the reason for the corrosion Hendershot experienced in the coffe can liner was due to galvanic dissimilar metals corrosion which I was familiar with in the military working with aluminium frame components and various different metals being attached. we simply used an appropriate dissimilar metals tape between surfaces. Im sure your probably familar with that however. to bad Lester didnt get to do the same.

Can't download anymore - it's setup so anything over 50 Megs (about 13 downloads) exceeds the limit allowed at that site. Could someone upload it elsewhere? I think sendspace.com is easy, no sign up needed and may allow more downloads.

Should, according to the current owner during the commissioning
Lester Hendershot have brought a 60 watt bulb to light up

This version will be known to you safely from the Internet:

In the footer of this brochure in the background is my opinion, "By Arthur C. Aho".

Here one sees the buzzer.

Both electromagnets are similar from a bell expanded and the metal strip in which the two electromagnets are secured (at the side where the connector contacts), fixed to the piece of Plexiglas and slidably connected to the spindle to the magnet / sheet metal strip.
This can be seen on the last picture in this document one more time.
The DC resistance of the two coils in series is 6 ohms.
The magnet is 5 inches wide, 1.5 inches deep, and 1 inch high.
The metal strip is 5 inches wide and 1 inch high.
The external dimensions of the electromagnet are: 2.5 inch length at 1 inch diameter.
The diameter of the enamelled copper wire is about 0.51 mm or about AWG 24

From a report by Skilling I learned that the buzzer is the interior of a larger built headphone speaker. I can not quite understand that on a magnetic speakers (see diagram), which in my opinion, this arrangement comes During the next wound coils on the costs associated with the magnetic poles of iron bars. Then when a voltage is generated at the coil magnetic field would be superimposed on the magnetic field of the permanent magnet and thereby modulate the magnetic flux through the iron rods and the iron membrane. The air gap between the iron rods and the membrane can be adjusted in such headphones via a thread. That lasts again a similarity to the buzzer.

Ma = magnet, S = coil, Me = iron membrane
Furthermore shows Skilling, Hendershot had used during his early attempts headphones and when he heard a scratching noise "scratching sound", this was the sign that the generator is now in operation and was unable to give a performance.
In the development and increased capacity of the generator has run this "Loud Speaker" larger dimensions and a part of the generator.

This is the "left" PCU.
I had always wondered what else should be that TEST "point".
This detail photo and the diagram (see below) it is clear

The coil is wound flat on the bottom section of the wire coil is, look at the two "+ contacts" of the former duo TM58 - "clipped" electrolytic capacitors.

This is the wire coil of the "right" PCU. Again, the ground pin of the former duo TM58 Elko's is brought out. He was pushed to the test directly to the terminal contact of the lamp base. I have it shown by dotted lines in the diagram

View of the transformer / transformer in the "left" PCU.
It is an American 110V to 6.3 V power transformer.
The metal used in this version of the PCU's rings are made of cold rolled mild steel and thus are magnetic. They are spot-welded at the seam multiply / overlap point. The inner diameter of the metal rings is 5.25 inches, and a height of 2.75 inches.

The circuit reminds me rather of the information published by Skilling and O'Brian diagrams. What is new is the presentation of lampwork capacitors in the PCU's. The mass foils us connections of the former Pyramids TM58 Duo electrolytics I have with drawn because they are used in this circuit.

All unmodified capacitors have a capacitance of 40μF at 110V AC.

I have canceled the pictures because I'm not in the mood to create the basis for lau any item in any "free energy" Newspapers / Manuals.
To replace the devalued against not good, I have seen images / movies etc. regarding this topic, I'm ready.
If interested please crusty7@gmx.de

Strikes me that the only thing different in this description when compared to Hendershot's original working devices relates to the metal being used.
The original cores were cut from good old fashioned 1940-50's tin cans.
They don't make them like this any more, yet originals are still available on e-bay as collectors pieces;-

Im sorry if its already been posted I ran across this site and posted it.

Did Hendershot invent the alternator we use today, but his self ran? very interesting.

What would happen if we connected the sandwiched coil to a cap and arranged permenant magnets around the perimeter of the claws, or just a horseshoe magnet as Hendershot seemed to favor.
Changing the capacity would change the frequency that the claws flipped their poles.

Just some thoughts, wondering how he got this arrangement to self run.

just a note of thought -it is evident that there is initially a prime-mover to Hendershots devices and I dont personally belive it is the magnetic oscillator (my opinion- as all you know the worth) , however the movers in his device are: 1- coils
2-capacitors
3-cores
4-magnet
It occured to me that tesla was his mentor, and that he was supposedly knowledgeable of his inventions and patents. remembering that when studying the schematic I was thinking just why in the hell would he destroy a perfectly good capacitor and then put it back together to use it in a disrupted manner? there had to be a reason and a method to his madness. then when I saw the schematic again the picture of Teslas radient energy device came to mind! (thumbnail below) I believe he was useing the long piece of salvaged foil as his antenna plate for receiving the radient potential and at the same time useing the two short pieces of foil as a transmitter to power the initial L1 coil to consequently operate the rest of the device.

consider it a reversal of the normal transmitter-receiver relationship. I believe the energy in the disrupted capacitor elements would begin to amplify as the L1 coil itself would begin to alternate and definetly bring the circuits to life.

Just my thoughts, but all of us know some method brought these units to life!

PS: He also placed concern on keeping the frequency on both of the disrupted capacitors exactly the same. which was another possible use of the test points in the circuit and during normal use those points were open. If just being open all the time then what would any purpose for the disrupted capacitors be other than the KEY initial mover?

Hey Clarence I noticed that too, its said he built several different versions, I think the transformers would work better in the magnetic field of the basket coils than the caps.
I found these caps at mouser 1000 uf capacitor Film Capacitors | Mouser Im not sure if they will work what do you guy's think they are not electrolytic they are film used in dc filtering.

Hello Dave45,

clarence,
I dont know about the use or nonuse of those capacitors - however I DID find some for 500v AC in both 500uf and the 1000uf values. they are made by ELECTRICON, INC- I believe in germany and they are power caps.
500uf 500v #E62.R17-504M10
1000uf 500v #E62.S24-105C20
you will have to find a distributor. just thought I would pass it on. LOL
mike, onward!

Hey Clarence,
Interesting observation the cap and coil create an LC circuit on both sides and the way the cap is made it could be drawing energy.

If we have two LC circuits in the same circuit they must be working 180 out of phase, they are bouncing energy back and forth across the buzzer coils.

Hello Dave45,

clarence,
presuming that the remade caps are radient energy receivers for each half of the push pull and do act as the prime movers there has to be a "traffic cop" per say to allow the initial direction of voltage and current flow through each half of the circuit so that everything always flows in unison. I will say that that traffic cop is the MAGNET with its N and S poles pointing in the initial direction of flow. once that flow is initiated I believe all of the caps themselves will tend to keep the alternation in order. also the orientation of all the coils windings and the "dot" codes of the transformers themselves should be observed. you are correct I believe when you say this is a perfectly balanced system.

the next main item I have been considering is the "oscillation of the buzzer " and how it is effected in order to maintain the whole push pull operation frequency perfectly. there is a whole lot going on in this "junkyard invention" that doesn't first meet the eye thats for sure!

I am curious to know what your thoughts on the buzzer would be. love to hear them.
mike, onward!
